2. Review of Performance Based Standards for Level 3 and 4 vehicles
Marcus Coleman PBS Conference – 6 March 2013

3. Context Limited uptake of Level 3 and 4 vehicles
Alternative schemes facilitating safer and more productive vehicles
Desire for a nationally consistent framework
Limited uptake of Level 3 and 4 vehicles because PBS offers little advantage compared with vehicles available under alternative schemes
Non PBS combinations have provided safety and productivity benefits and yet are unable to meet PBS requirements

4. Key Questions What is limiting the uptake of Level 3 and 4 vehicles?
How can the standards be changed to encourage safer and more productive Level 3 and 4 vehicles?

5. Key Questions How do we currently define safer and more productive?
Can we redefine safer?
